Description

Technical Field

[0001] This invention belongs to the field of instrument auxiliary equipment technology, and in particular relates to a power controller testing and inspection device. Background Technology

[0002] With the development of electronic technology, various power controllers are increasingly widely used. These power controllers can be used to realize functions such as power amplification, communication, and human-computer interaction. Depending on the application conditions, the internal structure of the power controller is also different. After the power controller is manufactured and assembled, it needs to be inspected before leaving the factory. After it is electrically connected to the corresponding load, the relevant functions of the power controller are verified to see if they meet the requirements.

[0003] In the prior art, patent document with authorization announcement number "CN104348143B" discloses a method and system for verifying the correct operation of an arc fault / transient detector. The method includes providing a power supply system; selectively switching a test switch and a circuit breaker switch to: a) provide electrical continuity from the short-circuit loop to ground, thereby establishing a short circuit between the output of the circuit breaker switch and ground; and b) inject current flow from the power supply into the short circuit, and / or c) terminate the injected current flow from the power supply into the short circuit; using the arc fault / transient detector to monitor the rate of change of one or both of the transient current and transient voltage in the short-circuit loop induced by the injection / termination of current flow from the power supply into the short circuit; and determining the functional state of the detector based on the monitoring, wherein malfunction of the detector corresponds to satisfying the condition that the detector cannot detect the induced rate of change during the monitoring process. This patented technical solution, by providing a load and simulating the system operating environment, achieves a concrete verification of the system's functionality.

[0004] However, some power controllers can be applied to multiple conditions. In the process of verifying the relevant functions of the power controller, it is necessary to electrically connect multiple loads to the power controller one by one, which is cumbersome. In addition, in the process of verifying the relevant functions of the power controller, some spare auxiliary tools are often discarded or placed randomly by the operator due to their short usage time, resulting in a messy placement of auxiliary tools and making it inconvenient for the operator to select the corresponding auxiliary tools again. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a power controller testing and inspection device.

[0006] The present invention is achieved through the following technical solutions.

[0007] This invention provides a power controller testing and inspection device, comprising a load chamber and a storage dish. The load chamber includes multiple horizontal supports, each with a positioning hole on its surface. The storage dish includes a tray, a support rod, and a U-shaped hook. One side of the hook fits into the positioning hole, and the other side of the hook is fixedly connected to one end of the support rod. The other end of the support rod extends outward and is also fixedly connected to the tray.

Detailed Implementation

[0020] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0021] like Figures 1 to 13 As shown, the present invention provides a power controller testing and inspection device, including a load chamber 1 and a storage dish 2. The load chamber 1 includes multiple horizontal supports 3, and the surface of the horizontal supports 3 is provided with positioning holes 4. The storage dish 2 includes a tray 5, a support rod 6 and a U-shaped hook 7. One side of the hook 7 is fitted into the positioning hole 4, and the other side of the hook 7 is fixedly connected to one end of the support rod 6. The other end of the support rod 6 extends outward, and the support rod 6 is also fixedly connected to the tray 5.

[0022] By adopting the technical solution of the present invention, during the verification of the relevant functions of the power controller, some auxiliary tools or consumables used by the operator can be temporarily stored in the tray, preventing the operator from arbitrarily discarding the auxiliary tools or consumables, keeping the auxiliary tools or consumables neatly arranged, and making it convenient for the operator to select them again.

[0023] Specifically, there are two support rods 6, which are fixedly connected to the front and rear sides of the tray 5 respectively. Preferably, the support rods 6 are both made of steel tubing. The technical solution of this invention allows the storage dish and the load compartment to be quickly assembled or disassembled, facilitating flexible use.

[0024] In addition, the load compartment 1 also includes multiple longitudinal supports 8, multiple vertical columns 9, and multiple side panels 10. There are multiple transverse supports 3. The longitudinal supports 8 are fixed between two adjacent transverse supports 3, and the vertical columns 9 are fixed between two adjacent transverse supports 3, or vice versa. Furthermore, the transverse supports 3, longitudinal supports 8, and vertical columns 9 are also fixed to the side panels 10. The longitudinal supports 8, vertical columns 9, and transverse supports 3 are all made of shaped steel pipes. Positioning holes 4 are provided on the top surface of the transverse supports 3, and limiting holes 11 are provided on the bottom surface of the transverse supports 3. At least one side of the hook 7 is fitted into the limiting hole 11. Using the technology of this invention, the hook 7 is simultaneously inserted into both the positioning hole 4 and the limiting hole 11, making the attachment between the container and the load compartment more stable and increasing the container's load-bearing capacity.

[0025] In addition, the load compartment 1 also includes a door 12, and one of the vertical columns 9 is hinged to the door 12. The power controller testing and inspection device also includes a control compartment 13, a support 14, a knob 15 and a wiring harness 16. One side of the support 14 is provided with a directional hole 17, and the other side of the support 14 is fixed to the longitudinal support 8. The control compartment 13 is hinged to the cross support 3. The surface of the control compartment 13 is provided with a knob 15, a touch screen 18, a main socket 19 and control buttons 20. The knob 15 also passes through the directional hole 17. The control compartment 13 is also provided with a controller 21. The touch screen 18, the main socket 19, and the control buttons 20 are electrically connected to the controller 21. The load compartment 1 is also provided with multiple load boards 22. The surface of each load board 22 is provided with a load 23 and a bypass socket 24, and the load 23 is electrically connected to the bypass socket 24. One end of the wiring harness 16 is provided with a main plug 25, and the other end of the wiring harness 16 is provided with multiple bypass plugs 26. By adopting the technical solution of the present invention, since the connection harnesses between multiple loads and the controller are concentrated together, during the verification of the relevant functions of the power controller, the operator only needs to connect the main plug 25 to the main socket 19 once, and connect the bypass socket 24 to the bypass plug 26 accordingly. This allows multiple loads to be connected to the controller at the same time. The controller can directly connect the power to the required load and turn off the power to the other loads to realize load switching, thereby verifying the operation of the power controller under various working conditions.

[0026] Specifically, load 23 is a DC regulated power supply, resistor box, signal generator, or CAN analyzer. The directional hole 17 is an oval through-hole, and its length is an arc. Control buttons 20 include an emergency stop button and a start / stop button.

[0027] In addition, the power controller testing and verification device also includes a chassis 27, a slewing bearing 28, a support cylinder 29, and an electric push rod 32. The chassis 27 is fixedly connected to multiple casters 30, and the chassis 27 is also fixedly connected to the outer ring of the slewing bearing 28. The inner ring of the slewing bearing 28 is fixedly connected to the support cylinder 29. The electric push rod 32 is hinged inside the support cylinder 29. The cross brace 3 is also fixedly connected to the bottom plate 31, and the piston rod of the electric push rod 32 is also hinged to the bottom plate 31. A bypass socket 24 is also provided at the control end of the electric push rod 32. There are two or more electric push rods 32, arranged in a circumferential array on the inner wall of the support cylinder 29. The slewing bearing 28 is a crossed roller bearing. The casters 30 are swivel wheels equipped with foot-operated brake calipers. Using the technical solution of this invention, the operator can also drive the electric push rod 32 through the controller to adjust the relative height between the control cabin and the ground to match the operator's height. The support cylinder 29 and the chassis 27 can also rotate relative to each other so that the control cabin faces the operator, which is convenient for the operator to carry out testing work. The relative tilt angle between the control cabin and the load cabin can also be adjusted accordingly, so that the operator can easily observe the data information displayed on the touch screen.
